A construction worker at a dam in Colombia was nearly knocked off his feet and buried under raging floodwaters of the Cauca River.

Video provided by Ruptly news agency captured the intense moment that workers, at the Ituango Dam project, are seen escaping massive waves. One of them, who failed to catch up with the rest and was left behind, finds himself perilously close to a ramping wave when it gets out of control.

Within mere seconds of the outburst he is chased by an immense snarling wave.By the time he reaches his colleagues, flood water had already engulfed the site.The incident took place on Wednesday at the construction site of the almost completed dam. The dam, the largest hydroelectric project in Colombia, had a blocked tunnel on Saturday, which led to flooding.
